About this trial

The aim of this study is to evaluate the agreement between subjective and objective toric lens prescriptions.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

They are at least 18 years of age.

They understand their rights as a research participant and are willing and able to sign a Statement of Informed Consent.

They have spherical refractive error at the corneal plane between +4.00 to -7.00DS

They have refractive astigmatism at the corneal plane of 0.75 to 2.25DC in one eye.

Disqualifiers

Is participating in any concurrent clinical or research trial.

They have an ocular disorder which would normally contra-indicate contact lens wear.

They have a systemic disorder which would normally contra-indicate contact lens wear.

They are pseudophakic or aphakic.
